I can confirm.... Tata Sky HD and Tata Sky HD PLUS both output HD on YPbPr (component) output. You do not (I repeat, You do not) need a converter.Essentially every VGA connector is basically a different form YPbPr connector. These are pin-compatible, meaning you can create a YPbPr to VGA connector by just soldering the right connections, you don't need to put any circuitry in beteeen
I created by my own YPbPr to VGA cable. There are many available in market for 300 to 1000.
